What are you runnin on your Dart/Duster?

It really depends on what size rim you want to use. When I bought the car it had 15" rear and 14" front. I didn't want that, and when I put my Dana in, the disc brake conversion made the calipers hit the rims. It was a golden opportunity to go 15" all around. I can tell you that I run 15X8 in the back with P295/50R15 BFG Radial TA. An 8" rim is really pushing it for that wide a tire. They are maybe a quarter inch from the leaf spring. There is no going wider without tubbing it out and moving the spring mounts. The fronts I went with 15X6 and P205/60R15. I tried P215/65R15 and they fit, but I was worried about clearing if I hit a bump. Also, I wanted about the same overall diameter as my old rear tires, which were a bit smaller. I like the look, it fills the wheel wells pretty nicely, and I don't ever have a tire hit or rub. What more can you ask?
